sampling : refactor init to use llama_sampling_params (#3696)

* sampling : refactor init to use llama_sampling_params

* llama : combine repetition, frequency and presence penalties in 1 call

* examples : remove embd-input and gptneox-wip

* sampling : rename penalty params + reduce size of "prev" vector

* sampling : add llama_sampling_print helper

* sampling : hide prev behind API and apply #3661

-### Examples for input embedding directly
-
-## Requirement
-build  `libembdinput.so`
-run the following comman in main dir (../../).
-```
-make
-```
-
-## [LLaVA](https://github.com/haotian-liu/LLaVA/) example  (llava.py)
-
-1. Obtian LLaVA model (following https://github.com/haotian-liu/LLaVA/ , use https://huggingface.co/liuhaotian/LLaVA-13b-delta-v1-1/).
-2. Convert it to ggml format.
-3. `llava_projection.pth` is [pytorch_model-00003-of-00003.bin](https://huggingface.co/liuhaotian/LLaVA-13b-delta-v1-1/blob/main/pytorch_model-00003-of-00003.bin).
-
-```
-import torch
-
-bin_path = "../LLaVA-13b-delta-v1-1/pytorch_model-00003-of-00003.bin"
-pth_path = "./examples/embd-input/llava_projection.pth"
-
-dic = torch.load(bin_path)
-used_key = ["model.mm_projector.weight","model.mm_projector.bias"]
-torch.save({k: dic[k] for k in used_key}, pth_path)
-```
-4. Check the path of LLaVA model and `llava_projection.pth` in `llava.py`.
-
-
-## [PandaGPT](https://github.com/yxuansu/PandaGPT) example (panda_gpt.py)
-
-1. Obtian PandaGPT lora model from https://github.com/yxuansu/PandaGPT. Rename the file to `adapter_model.bin`. Use [convert-lora-to-ggml.py](../../convert-lora-to-ggml.py) to convert it to ggml format.
-The `adapter_config.json` is
-```
-{
-  "peft_type": "LORA",
-  "fan_in_fan_out": false,
-  "bias": null,
-  "modules_to_save": null,
-  "r": 32,
-  "lora_alpha": 32,
-  "lora_dropout": 0.1,
-  "target_modules": ["q_proj", "k_proj", "v_proj", "o_proj"]
-}
-```
-2. Papare the `vicuna` v0 model.
-3. Obtain the [ImageBind](https://dl.fbaipublicfiles.com/imagebind/imagebind_huge.pth) model.
-4. Clone the PandaGPT source.
-```
-git clone https://github.com/yxuansu/PandaGPT
-```
-5. Install the requirement of PandaGPT.
-6. Check the path of PandaGPT source, ImageBind model, lora model and vicuna model in panda_gpt.py.
-
-## [MiniGPT-4](https://github.com/Vision-CAIR/MiniGPT-4/) example (minigpt4.py)
-
-1. Obtain MiniGPT-4 model from https://github.com/Vision-CAIR/MiniGPT-4/ and put it in `embd-input`.
-2. Clone the MiniGPT-4 source.
-```
-git clone https://github.com/Vision-CAIR/MiniGPT-4/
-```
-3. Install the requirement of PandaGPT.
-4. Papare the `vicuna` v0 model.
-5. Check the path of MiniGPT-4 source, MiniGPT-4 model and vicuna model in `minigpt4.py`.
